Zusammenfassung:	Anaerobic membrane bioreacter (AnMBR), an combination of methane fermentation and membrane technology, have recently been attracting attention as a creation energy and energy saving wastewater treatment method. AnMBR has not yet been used for treating real sewage because related knowledge is not enough. In this study, long-term continuous treatment experiment of real sewage using AnMBR was conducted to evaluate the treatment performance. Hydraulic retention time (HRT) was shorted stepwise from 24 h to 4 h. As a result, high COD removal efficency (84 to 90%) was obtained in whole experiment. In particular, a high treated water quality with BOD
